Fresh perspectives, architecture deep-dives, and lessons from building AI systems.
Enterprise AI Workflow Patterns: Autonomy vs Control
Choose between single inference, fully autonomous agents, deterministic workflows, and guided hybrid agents. Comparison matrix, JSON contracts, and when to escalate from one call to a full agent.
ARCOne Agent with Routes vs Specialized Agents: When to Split
Enterprise agent architecture: when a shared runtime with governed routes is enough, and when different execution boundaries require specialized agents.
ARCAgent Identity: Who Is Asking vs Which Software Is Acting
User identity answers who is asking; agent identity answers which software is acting. Least privilege, audit, revoke, and dual gateway checks for real-time and batch.
ARCSpotify Music Discovery: Inverted Index Search Explained
System design of inverted index search with a Spotify worked example: catalog vs index, title artist album lyrics postings, autocomplete, fuzzy match, ranking, and play hydration.
ARCSpotify Music Streaming Pipeline: From Upload to Search and Play
How a Spotify-class stack turns a master upload into searchable catalog and playable audio: ingest, multi-bitrate encode, search index, multi-CDN delivery, and client ABR over HTTP range requests.
EXPAfter Training an LLM: From Frozen Weights to Token-by-Token Inference
What happens once training stops: frozen weights, prefill vs decode, sampling, the KV cache, and the serving tricks that make inference faster without changing what the model knows.
EXPAligning an LLM: From Autocomplete to Assistant
How SFT and preference tuning (RLHF/DPO) turn a pre-trained next-token model into a helpful assistant: same training loop, different data, thin layer that shapes behavior not knowledge.
EXPDuring Training an LLM: From Random Weights to a Working Model
What happens inside the weight tensors as an LLM trains: random initialisation, the four-step training loop (forward, loss, backprop, optimizer), and what each component learns as a next-token model.
